Description

Technical Field

[0001] This utility model specifically relates to a homogenizing device for modified asphalt processing, belonging to the field of asphalt processing technology. Background Technology

[0002] Modified asphalt is a new type of asphalt material made by adding modifiers such as rubber, resin, and polymers to ordinary petroleum asphalt and processing it through specific processes. By changing the chemical composition and microstructure of asphalt, it significantly improves high-temperature stability, low-temperature crack resistance, aging resistance, and bonding performance, and is widely used in highways, bridge paving, waterproofing projects, and other fields.

[0003] The performance improvement of modified asphalt is highly dependent on the uniform mixing of each component during the processing. Therefore, special homogenizing equipment is required to achieve full integration of the modifier and the base asphalt. Through the synergistic effect of mechanical force and heat energy, the aggregated state of the modifier is broken, so that it is uniformly dispersed in the asphalt system.

[0004] Currently, mixing rods are commonly used for homogenization in modified asphalt processing. However, the mixing position of existing equipment is mostly fixed. Due to the viscosity of asphalt, the bottom material is more directly affected by the mixing rod during the mixing process, while the upper material is only indirectly mixed by the fluid. This results in a significant difference in mixing intensity between the upper and lower layers, which can easily lead to uneven dispersion of modifiers in certain areas. In addition, due to the viscosity of asphalt, some asphalt may adhere to the inner wall of the mixing tank, affecting subsequent use. Therefore, this application provides a homogenization device for modified asphalt processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a homogenizing device for modified asphalt processing, so as to maintain uniformity between the upper and lower mixing layers during the mixing process.

[0006] To further achieve the above objectives, the following technical solution is adopted:

[0007] A homogenizing device for modified asphalt processing includes a support frame, a mixing tank fixedly connected to the top of the support frame, a T-shaped block slidably disposed on the top of the support frame, a support block fixedly connected to one end of the T-block, a mixing shaft rotatably connected through the surface of the support block, a mixing mechanism installed on the outer wall of the mixing shaft, and an adjustment mechanism installed on the top of the support frame.

[0008] Preferably, the adjustment mechanism includes a first fixing block fixedly connected to the top of the support frame, a second fixing block fixedly connected to the top of the support frame, a lead screw rotatably connected inside the first fixing block, a lifting motor fixedly connected to the top of the first fixing block, the output end of the lifting motor fixedly connected to the top of the lead screw, and one end of the T-shaped block threadedly connected to the outer wall of the lead screw.

[0009] Preferably, a guide post is fixedly connected inside the second fixing block, and the end of the T-shaped block away from the lead screw is slidably connected to the outer wall of the guide post.

[0011] Preferably, the auxiliary component includes two stirring shafts symmetrically and rotatably connected inside the support block. Multiple stirring blades are fixedly connected from top to bottom to the outer walls of both stirring shafts. These blades are staggered with the first stirring blade. The top ends of both stirring shafts are rotatably connected inside the support block. A gear is fixedly connected to the outer wall of the first stirring shaft. Gears are fixedly connected to the top ends of both stirring shafts. Both gears mesh with the first gear. Both gears are located on the top surface of the support block.

[0012] Preferably, both sides of the plurality of stirring blades one and two are fixedly connected with a plurality of serrations.

[0013] Preferably, the top of the support plate is symmetrically fixed with silicone scrapers, one side of each of the two silicone scrapers is in contact with the inner wall of the mixing tank, a fixing ring is fixedly connected to the outer wall of the bottom end of the mixing shaft, and an arc-shaped scraper is fixedly connected to the outer wall of the fixing ring, the bottom surface of the arc-shaped scraper is in contact with the bottom surface of the inner side of the mixing tank.

[0014] Preferably, a discharge pipe is fixedly connected to the bottom of the mixing tank, and a solenoid valve is fixedly connected to the outer wall of the discharge pipe.

[0015] Beneficial effects:

[0016] 1. This application is equipped with an adjustment mechanism. During the mixing process, the adjustment mechanism can be activated simultaneously. Through the reciprocating lifting and lowering of the adjustment mechanism, the mixing mechanism can be driven to move up and down inside the mixing drum. This effectively breaks the difference in mixing intensity between the upper and lower layers formed when mixing in a fixed position. By dynamically adjusting the range of action, the asphalt at different heights in the equipment can be subjected to sufficient mechanical action, thereby improving the overall mixing quality of the modified asphalt.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6As shown, a homogenizing device for modified asphalt processing includes a support frame 1, a mixing tank 2 fixedly connected to the top of the support frame 1, a T-shaped block 3 slidably disposed on the top of the support frame 1, a support block 4 fixedly connected to one end of the T-shaped block 3, a mixing shaft 5 rotatably connected through the surface of the support block 4, a mixing mechanism installed on the outer wall of the mixing shaft 5, an adjustment mechanism installed on the top of the support frame 1, a discharge pipe 23 fixedly connected to the bottom of the mixing tank 2, and a solenoid valve 24 fixedly connected to the outer wall of the discharge pipe 23.

[0027] In use, the materials for processing modified asphalt can be poured into the mixing tank 2 first. Then, the adjusting mechanism can be activated to drive the T-block 3 and support block 4 to gradually descend, thereby moving the mixing mechanism into the mixing tank 2. At this time, the mixing mechanism can be started. The mixing mechanism can fully mix the asphalt and modifier, significantly improving the mixing uniformity and ensuring the consistency of the modified asphalt performance. At the same time, the adjusting mechanism can also be activated during the mixing process. By reciprocating up and down of the adjusting mechanism, the mixing mechanism can be driven to move up and down inside the mixing tank 2. This effectively breaks the difference in mixing intensity between the upper and lower layers formed when mixing in a fixed position. When the mixing mechanism moves downward, it can enhance the shearing and turning of the high-viscosity asphalt at the bottom. When it moves upward, it can bring the insufficiently mixed asphalt in the upper layer into the mixing area. By dynamically adjusting the range of action, the asphalt at different heights in the equipment can be fully subjected to mechanical action, thereby improving the overall mixing quality of the modified asphalt.

[0028] Reference Figure 1 and Figure 2 The adjustment mechanism includes a first fixed block 6 fixedly connected to the top of the support frame 1, a second fixed block 7 fixedly connected to the top of the support frame 1, a lead screw 8 rotatably connected inside the first fixed block 6, a lifting motor 9 fixedly connected to the top of the first fixed block 6, the output end of the lifting motor 9 fixedly connected to the top of the lead screw 8, one end of the T-shaped block 3 threadedly connected to the outer wall of the lead screw 8, a guide post 10 fixedly connected inside the second fixed block 7, and the end of the T-shaped block 3 away from the lead screw 8 slidably connected to the outer wall of the guide post 10.

[0029] When in use, the lifting motor 9 can be started to drive the lead screw 8 to rotate. Since one end of the T-shaped block 3 is threadedly connected to the lead screw 8, the rotation of the lead screw 8 can drive the T-shaped block 3 to move up and down, thereby moving the stirring mechanism back and forth inside the stirring tank 2. At the same time, since one end of the T-shaped block 3 is also slidably connected to the outer wall of the guide column 10, the T-shaped block 3 is more stable when moving up and down, avoiding the phenomenon of uneven stirring caused by shaking during the stirring process.

[0030] Reference Figure 1 , Figure 3 and Figure 4The stirring mechanism includes multiple stirring blades 11 fixedly connected from top to bottom to the outer wall of the stirring shaft 5. A support plate 12 is fixedly connected to the outer wall of the stirring shaft 5. A connecting block 13 is fixedly connected to the top of the T-shaped block 3. A stirring motor 14 is fixedly connected to the top of the connecting block 13. The output end of the stirring motor 14 is fixedly connected to the top of the stirring shaft 5. An auxiliary component is provided inside the support block 4.

[0031] When in use, the mixing motor 14 is started first, which drives the mixing shaft 5 to rotate rapidly. At this time, the rapid rotation of the mixing shaft 5 will drive multiple mixing blades 11 to rotate inside the mixing tank 2. Through the multiple mixing blades 11, the modified asphalt inside the mixing tank 2 can be effectively mixed and blended, making it more uniform.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The auxiliary components include two stirring shafts 15 symmetrically and rotatably connected inside the support block 4. Multiple stirring blades 16 are fixedly connected from top to bottom on the outer walls of the two stirring shafts 15. The multiple stirring blades 16 are staggered with the multiple stirring blades 11. The top ends of the two stirring shafts 15 are rotatably connected inside the support block 4. A gear 17 is fixedly connected to the outer wall of the stirring shaft 15. A gear 18 is fixedly connected to the top ends of the two stirring shafts 15. The two gears 18 are meshed with the gear 17. The gear 17 and gear 18 are both located on the top surface of the support block 4. Multiple serrations 19 are fixedly connected to both sides of the multiple stirring blades 11 and 16.

[0033] During use, as the stirring motor 14 drives the stirring shaft 5 to rotate, it also drives the gear 17 to rotate. Since both gears 18 are meshed with the gear 17, the rotation of the gear 17 causes the two gears 18 to drive the two stirring shafts 15 to rotate continuously. This causes the two stirring shafts 15 to drive multiple stirring blades 16 to stir in different directions inside the mixing tank 2. Through multiple intersecting stirring blades 11 and 16 with different stirring directions, the asphalt and modifier can be fully mixed, significantly improving the mixing uniformity and ensuring the consistency of the modified asphalt performance. At the same time, during the rotation of the stirring blades 11 and 16, the multiple serrations 19 on their surfaces can also shear the materials in contact, effectively breaking up the modifier agglomerates and promoting their uniform dispersion in the asphalt, so that the materials can be mixed more evenly.

[0034] Reference Figure 3 , Figure 4 and Figure 5The top of the support plate 12 is symmetrically fixed with silicone scrapers 20. One side of each silicone scraper 20 is in contact with the inner wall of the mixing tank 2. The bottom of the mixing shaft 5 is fixedly connected with a fixing ring 21. The outer wall of the fixing ring 21 is fixedly connected with an arc-shaped scraper 22. The bottom surface of the arc-shaped scraper 22 is in contact with the bottom surface of the mixing tank 2.

[0035] During use, as the stirring shaft 5 rotates, it also drives the support plate 12 and the bottom fixing ring 21 to rotate. Because one side of the two silicone scrapers 20 is in contact with the inner wall of the mixing tank 2 and the bottom of the arc-shaped scraper 22 is in contact with the bottom surface of the inner wall of the mixing tank 2, the rotation of the support plate 12 and the fixing ring 21 will cause the two silicone scrapers 20 and the arc-shaped scraper 22 to scrape the inner wall and bottom of the mixing tank 2 respectively. This can efficiently clean the asphalt adhering to the inner wall of the mixing tank 2, avoid asphalt accumulation affecting the subsequent processing quality, and at the same time, it will not damage the inner wall of the tank, thus extending the service life of the equipment.

[0036] As a technical optimization of this utility model: First, the material for processing modified asphalt is poured into the mixing tank 2. Then, the lifting motor 9 is started to drive the lead screw 8 to rotate. Since one end of the T-shaped block 3 is threadedly connected to the lead screw 8, the rotation of the lead screw 8 can drive the T-shaped block 3 and the support block 4 to gradually descend, thereby moving the mixing shaft 5 into the mixing tank 2. At this time, the mixing motor 14 can be started to drive the mixing shaft 5 to rotate rapidly. According to the rapid rotation of the mixing shaft 5, multiple mixing blades 11 will rotate inside the mixing tank 2. The multiple mixing blades 11 can effectively mix the modified asphalt inside the mixing tank 2, making it more uniform. As the mixing motor 14 drives the mixing shaft 5 to rotate, it will also drive the gear 17 to rotate. Since both gears 18 are meshed with gear 17, the rotation of gear 17 will cause the two gears 18 to drive the two mixing shafts 15 to rotate continuously. In this way, the two mixing shafts 15 drive multiple mixing blades 16 to move in different directions inside the mixing tank 2. The mixing process, achieved through multiple intersecting mixing blades 11 and 16 with different mixing directions, ensures thorough mixing of asphalt and modifier, significantly improving mixing uniformity and guaranteeing the consistency of modified asphalt performance. Simultaneously, during the rotation of mixing blades 11 and 16, the multiple serrations 19 on their surfaces shear the contacting material, effectively breaking up modifier agglomerates and promoting their uniform dispersion in the asphalt. This results in a more uniform mixing of materials. Furthermore, as the mixing shaft 5 rotates, it further... This causes the support plate 12 and the bottom fixing ring 21 to rotate. Since one side of the two silicone scrapers 20 is in contact with the inner wall of the mixing tank 2 and the bottom of the arc-shaped scraper 22 is in contact with the bottom surface of the inner wall of the mixing tank 2, as the support plate 12 and the fixing ring 21 rotate, the two silicone scrapers 20 and the arc-shaped scraper 22 will scrape the inner wall and bottom of the mixing tank 2 respectively. This can efficiently clean the asphalt adhering to the inner wall of the mixing tank 2, avoid asphalt accumulation affecting the subsequent processing quality, and at the same time, it will not damage the inner wall of the tank, thus extending the service life of the equipment.

[0037] Simultaneously, during the mixing process, the lifting motor 9 can be restarted to drive the lead screw 8 to rotate. Since one end of the T-shaped block 3 is threadedly connected to the lead screw 8, the rotation of the lead screw 8 can drive the T-shaped block 3 to move up and down, thereby moving the mixing mechanism back and forth inside the mixing tank 2. At the same time, since one end of the T-shaped block 3 is also slidably connected to the outer wall of the guide column 10, the T-shaped block 3 is more stable when moving up and down, avoiding the phenomenon of uneven mixing caused by shaking during the mixing process. This effectively breaks the difference in mixing intensity between the upper and lower layers formed when mixing in a fixed position. When the mixing mechanism moves downward, it can enhance the shearing and turning of the high viscosity asphalt at the bottom. When it moves upward, it can bring the unmixed asphalt in the upper layer into the mixing area. By dynamically adjusting the range of action, the asphalt at different heights in the equipment can be fully subjected to mechanical action, thereby improving the overall mixing quality of the modified asphalt.
